I like how Mat Lalonde is not afraid to slaughter the paleo sacred cows (so to speak) if they are not scientifically defensible. Now put your learnin’ hat on and get ready to go hard core into the science of nutrition.

Loren Cordain, the grandpappy of Paleo, gives a fascinating introduction to who we are and what we evolved to eat. Guess what? Eating more meat was one of the key changes that allowed a large, metabolically active brain to evolve.
